Based on a tunnel EIA report in Tianjin,the calculating method of NOX emmision rate in the tunnel was introduced and the dispersion concentration of NO2 was predicted by Gauss model.The result showed that the NO2 concentration would exceed the standard GB3095-1996 within the horizontal range of 129 meters from the stack and leeward between 69 meters and 73 meters high.The dispersion concentration of NO2 was predicted near the tunnel portal with TOP model,the NO2 concentration from the tunnel portal leeward to the distance of 30 meters would exceed the standard GB3095-1996.So the control method of air pollutant was promoted.

The construction of No.I line of Tianjin Subway will improve the current situation of city's traffic to a great extent, it exists an important meaning to promote the construction of Tianjun City and to push its ec onomic development forward. This engineering work will produce somewhat influenc es on city's ecologic environment during construction and operation periods. The positive and passive influences of the subway engineering works on the city's e cologic environment are analyzed in detail concerned with the following aspects, such as the noise, vibration, dush raising and soil erosion during the construc tion period, and pushing the economic development forward, relaxing traffic on g round level, improving environmental quality during the operation period, etc.

Alternate in EIA mainly includes the alternate of the technology, site-selection and environmental protection countermeasures. The content in the EIA of municipal sewage treatment plant has its own specific characteristics. In view of a lot of experience, discussion and case analysis of alternate was made by the example of several large municipal sewage treatment plants.
